western and western neighborhoods, the windchill is not a factor since the winds are calm. so overnight tonight, here's what we know. generally clear skies. it looks like by tomorrow morning, even before sunrise, we'll get a few clouds out there. not so breezy and very cold out in the suburbs. i think out there, lower to mid 20s, especially since the winds are lightening up. here in town, a low of 30 degrees or so. winds only out of the west at 5 to 10 miles per hour. we'll talk about the holiday weekend coming up and some of these numbers that i'm going to show you for highs look pretty good and next week, first week of 2012, looks like it's going to be very, very cold. wisdom. >> thanks gary. the republican president rnl candidates are just six days from learning who will win the first real votes in the race for the white house. with no clear front runner, the iowa caucuses seem to be up for grabs. tom fitzgerald has the story.
